Thank you, funnily enough that is more or less exactly what made me give up on the thing. Having made sure the routes were all there, via my PC at home, I took the Garmin on holiday full of confidence that I could rely on it. But when I switched it on it wouldn't show me anything useful. As technology goes, that is worse than useless as far as I'm concerned, as I don't trust it to work. So, basically, I wasted over a hundred quid.
